摘要: 分析了僵藕发生与矿质营养的关系。结果表明:①僵藕田土壤中有机质和有效性矿质离子含量均略低于正常田,但差异不显著;②在肥沃土壤中生长的僵藕叶中矿质元素含量一般均低于正常藕,根状茎中,锰、铜、铁、锌的含量极显著高于正常藕,钙显著低于正常藕;③僵藕栽培在营养液中,其子藕仍为僵藕,在矿质营养缺乏条件下的正常藕不发生僵化。因此,僵藕并非因矿质营养缺乏直接所致。

Abstract: mineral nutrition on development of stif lotus(Nelumbo,~cCera Gaertn.)were studied.results showed:①the contents of organic manure and efective mineral lements in stifen soil and noI/na]soil had rio significant diference;(1he IⅥn、Cu、Fe、 contents in son—rhizo~ of stif lotus were significantly higher than them in health lotus at 1% level,while the Ca content was sign/ficantly lower at 5% level;⑧1he son-rhizon' of stif lotus planted in lotus special medium and Soasland and Arrlon medium were also stifen,health lotus planted in 0.1%uI规were also hthy.So it can be confirmed that stif lotus was not caused by mineral elements deficiency.

Key words: Nelumbo nucifera Gaertn., Stif lotus, Mineral nutrition
